The King City oil field, also referred to as the San Bernabe oil field, is 20 miles northwest of the San Ardo oil field, and 6 miles south of the town of King City, Monterey County, California. The field was discovered in December, 1959, the discovery well being the Thomas Doud Estate No. 2, which produced 16° gravity oil at the rate of 76 b/d net oil cutting 16% from a depth of 2,000 feet. The No. 3 was also completed in December, 1959, with an I.P. of 531 b/d cutting 0.1%. The No. 4 was completed in June, 1960, as a gas well indicating the possibility of a gas cap in the field. Cumulative production through September, 1960, is 43,000 bbls. of net oil and 10,000 bbls. of water. The producing sand is middle Miocene in age with a total thickness of 330 feet, about 150 feet of which is oil saturated. Porosity averages 23% and permeabilities have been found as high as 2,100 millidarcys. Accumulation is believed to be due to a combination of structure and stratigraphy. The discovery well was located primarily on the basis of field and subsurface geology.
